ZIAGEN ORAL SOLUTION Contraindications:
Presence of HLA-B*5701 allele. Prior hypersensitivity reaction to abacavir (see full labeling). Moderate or severe hepatic impairment.
ZIAGEN ORAL SOLUTION Warnings/Precautions:
Screen for presence of HLA-B*5701 allele prior to starting therapy or reinitiation; if (+), abacavir is contraindicated. Discontinue immediately if hypersensitivity is suspected, regardless of HLA-B*5701 status and even when other diagnoses are possible. If hypersensitivity cannot be ruled out, do not restart. If stopped for reasons other than hypersensitivity, restart only if medical care can be readily accessed. Suspend if lactic acidosis or pronounced hepatotoxicity (eg, hepatomegaly, steatosis) occurs. Possible risk of MI; minimize risk factors for coronary heart disease (eg, hypertension, hyperlipidemia, diabetes, smoking). Women. Obesity. Elderly. Pregnancy. Nursing mothers: not recommended.
